Kriegers Flak is an offshore wind farm system in the Baltic Sea . It consists of three parts / wind farms, each of which is located in the Exclusive Economic Zones (EEZ) of Denmark , Sweden and Germany and covers a total area of 132 square kilometers. The part in the Danish EEZ is under construction, the part in the German EEZ has been in operation as the Baltic 2 offshore wind farm since 2015 , the Swedish part is still in the planning phase. It is named after the under-sea reef Kriegers Flak .
Partial area Denmark
An installed capacity of 600 megawatts is planned here. The investment volume is estimated at up to 1.3 billion euros. Kriegers Flak will become the largest Danish offshore wind farm and will theoretically be able to supply around 600,000 households with electricity.
Vattenfall won the auction for the feed- in tariff in the Danish part of the wind farm in November 2016 at a price of 49.90 euros per megawatt hour . The upper limit of the auction, however, was 120 euros. At the time, this was the “lowest bid for an offshore wind farm in the world”. In November 2017 Vattenfall to implement it was announced 72 wind turbines of the type SG 8.0-167 DD , each with 8.4 MW rated power at Siemens, Gamesa commissioned.
The construction of the two transformer platforms, Kriegers Flak A and Kriegers Flak BE, took place in 2018. At the beginning of 2020, the two construction sites Kriegers Flak W and Kriegers Flak E around the two platforms were designated as restricted areas so that construction work can begin there. The installation of the wind turbines is to start from February 2021 and be completed by the end of the same year. The 72 monopile foundations are produced by the EEW Group in Rostock .
In addition to the right to state feed-in tariffs, Vattenfall has signed long-term electricity supply contracts with the Danish companies Novo Nordisk and Novozymes for the purchase of electricity from the wind farm. In December 2018, Vattenfall completed the financing of the project.
Part of Sweden
The Kriegers Flak II offshore wind farm is planned for the Swedish part of the area . The project with a possible output of 640 megawatts was originally developed with wpd since 2002 and sold to Vattenfall in 2005. A building permit from 2006 for 128 wind turbines expired in 2018. In the summer of 2020, Vattenfall asked for a permit for wind turbines with a height of up to 280 meters (instead of the previous 170 meters) and an extension of the deadline for the start of construction work.
Part of Germany
The EnBW Baltic 2 offshore wind farm has been located east of Kriegers Flak directly across the border in the German EEZ since the mid-2010s .
Combined Grid Solution
The offshore wind farm Baltic 2 is integrated into the German transmission network of 50Hertz Transmission with 150 kilovolts and the connection point in Bentwisch . The Kriegers Flak offshore wind farm will be connected to Energinet.dk's Danish transmission network with 220 kilovolts and the connection point in Bjæverskov Sogn . Since the two offshore wind farms are in close proximity, a connection enables the exchange of electricity between the countries. This German-Danish interconnector is called the Combined Grid Solution . The transmission capacity is 400 megawatts with two AC submarine cables . The project is included in the Federal Requirements Plan Act. Combined Grid Solution complements the high-voltage direct current transmission line Kontek between Germany and Denmark , which has existed since 1996 .
As part of a so-called “supergrid”, the Swedish electricity transmission network is also indirectly connected to the system with an overhead line between Zealand and Sweden.
The German and Danish AC transmission networks are asynchronous. The mains frequency is identical, but has a slightly shifted clock ( phase ). After completion of Kriegers Flak therefore and the interconnector, the German offshore wind farms are Baltic 1 and Baltic 2 to the phase of the Nordic composite system Nordel be changed. In order to be able to transport electricity from the three wind farms - and occasionally from Germany or Denmark to the respective other country, an HVDC close coupling was installed on the German side by the company ABB on the site of the 50Hertz Bentwisch substation near Rostock . This double converter converts alternating current after the Danish (Nordic) phase into direct current and directly afterwards into alternating current after the German continental European phase .
The project had an investment volume of 900 million euros. It was funded with 150 million euros by the European Commission as part of the European Energy Program for Recovery (EEPR).
After postponements, the line will go into operation in the second quarter of 2020.
